UPS/400 . . . an IBM AS/400 UPS power monitoring system . . .
SYSTEM ATTRIBUTES
The System Attributes display is used to identify the system parameters to be used by UPS/400 to create an orderly system shutdown during a power loss. During a trial period of UPS/400, the date the trial copy expires is displayed on the screen. This trial expiration date is 30 days after the date you installed UPS/400. After the system has been purchased and the copy made permanent, this information does not display.
Test mode for UPS/400: When UPS/400 is installed, the system is in Test mode. This is indicated by the flashing “*** Test mode ***” at the bottom right hand corner of the screen. Test mode allows the user to completely simulate a power loss as well as review the UPS/400 monitoring process that would take place if a real power loss had occurred. If you wish to run a simulation of the monitoring process, notify all users prior to the test as messages would be sent to their terminals, notifying them of a power loss. Test mode utilizes all intervals and notification specified in the System Attributes screen, but does not shut down any processes or execute user Exit Procedures. See the System Attributes (Test mode) page for a further explanation of this function.
The System Attributes screen contains default values. These should be reviewed/modified by the user as follows prior to starting UPS/400.
Interval: Intervals are expressed in minutes and are the times that UPS/400 will check system status and perform specified functions. At each interval, UPS/400 will notify the system operator and/or users with severity messages, begin specific processes and execute exit procedures. Six intervals are provided, although the user may use less than this number. Note: Intervals are used in calculation estimated power down times for severity messages. The first interval can be 0, which means that UPS/400 will issues its first message immediately upon power loss detection.
Intervals will be automatically adjusted when the remaining battery life is less than the last interval. A message will be sent to the system operator message queue of the adjusted percentage.
Notification - QSYSOPR: Specify (Y/N) if you wish UPS/400 to notify the system operator during a specified interval. Normally, the system operator would be notified (Y) at all times during a power loss situation.
Notification – Users: Specify is you wish UPS/400 to notify all active users during a specified interval. Notification of users is handled by severity messages ranging from level 1 (least severe) to level 3 (most severe – see Test mode for severity message text). If you do not wish to notify active users at a given interval, leave the field blank. The same severity message can be used at several intervals.
While in Test mode, messages will not actually be sent to users, but entries in the Current Status display will show as though they were sent.
Process: One or two processes may be specified at each interval. Valid processes are:
*JOBQ | Hold all specified job queues (F6). |
*SBS1 | End all specified subsystems in SBS1 (F7). |
*SBS2 | End all specified subsystems in SBS2 (F8). |
*INT | End all interactive users that are on the system. |
*PWRD | Power the system down. |
Processes *JOBQ, *SBS1, and *SBS2 are specified via
Exit Procedure: The exit procedure is used to specify user written programs that you wish UPS/400 to execute as part of the orderly power down process. These programs must complete processing within the duration of the current interval and the last interval. If processing does not complete in that time span, the
